NTA

Neighborhood Tabulation Areas are the city's statistical neighborhoods: boundaries drawn by the Department of City Planning by aggregating census geography into named areas that approximate recognized neighborhoods while remaining stable enough for data tabulation. They exist because 'neighborhood' has no legal definition in New York — real-estate usage, community identity, and administrative boundaries all disagree — and analysts need a consistent unit for comparing population, housing, and economic data across the city.

NTAs carry no regulatory force: zoning, community-district service boundaries, and school zones are all drawn independently of them. In property analysis they serve as the neighborhood-scale lens for contextual statistics, and as a reminder that any 'neighborhood' statistic depends entirely on whose boundaries produced it.
